Analyte evaluating device, and method for evaluating analyte
First Claim
1. An analyte evaluating device comprising:
- a carrier body that can be bound with an analyte having a fluorescence-labeled part that can emit fluorescence by light received when the distance between the fluorescence-labeled part and the carrier body is enlarged, the distance between the fluorescence-labeled part and the carrier body being variable by an external action;
a light irradiation device for the fluorescence-labeled part to emit light; and
a fluorescence detecting device for detecting the fluorescence emitted by the fluorescence-labeled part, wherein at least one factor selected from the group consisting of a light irradiation angle, a light irradiation intensity, a light irradiation area, a fluorescence detection angle, a fluorescence detection area, the shape of the carrier body, the surface area of the carrier body, a salt concentration in a medium for use in the detection, and the adhesion density of analytes on the carrier body, is adjustable.

Abstract
In an analyte evaluating device comprising a carrier body that can be bound with an analyte having a fluorescence-labeled part that can emit fluorescence by light received when the distance between the fluorescence-labeled part and the carrier body is enlarged, at least one factor selected from the group consisting of a light irradiation angle, a light irradiation intensity, a light irradiation area, a fluorescence detection angle, a fluorescence detection area, the shape of the carrier body, the surface area of the carrier body, a salt concentration in a medium for use in the detection, and the adhesion density of analytes on the carrier body, is made to be adjustable. A high sensitivity is realized. Evaluation is possible without introducing fluorescence-labeled parts. Evaluation for a tiny amount of sample is possible. It is also possible to evaluate objects in a mixed state. Miniaturized, complex, and integrated devices are possible.
